To all whom it may concern:

Be it known that we, JOHN B. KILBU'RN and EDWARD G. BUDD, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cushions, of which the following is a specification.

This invention relates to cushions and has reference particularly to cushions of the type adapted for use in car-seats.

The object of the invention is to effect certain improvements in the construction of cushions for this use, to the end that a cushion is produced which is quite soft, which is strong and durable, which can be manufactured at low cost, and which is constructed largely of metal, so that itis practically fireroof. P In accordance withthe invention, the cushion has a metallic frame consisting of four frame-members secured together at their ends. Some or all of these frame-members aresheetmietal strips, which are pressed to the desired forni, and these frame-members support a plurality of spiral springs, which dingly sustain the coveringofthe serve to yi These sheet-metal frame-members cushion.

are of channel-section, and the springs sup-- ported thereby are mounted upon the bottoms of these channels; for this reason, the springs may be of increased length, resulting in making the cushion softer and more durable on account of this greater len th of spring. The size of these sheet-metal amemembers is such that the sides thereof serve to support the spiral springs and reclude excessive lateral movement thereo In order to increase the strength of the frame-members, a plurality of metallic braces are referably employed, extending across the amemembers and secured at their ends to integral flanges formed at the lateral edges thereof. Preferably these members of the frame are formed to provide grooves at their outer edges adapted to receive strips of wood, paper or similar material, to which the edges of the covering material of the cushion may be secured by tacks. The central portion of the cushion is supported by spiral springs mounted upon metallic slats which extend across the frame and are secured at their ends to 0pposite members thereof. These slats are also of sheet-metal pressed into form and have integral upwardly-turned flanges at their latframe.

which the covering materia eral edges. The width of these slats is increased at intervals throughout their lengths at the points ofsupport of the spiral springs, so that the flanges at the latera edges curve about these points of support and partially surround the bases of the springs; in this way, the springs mounted upon the slats are 1 also held against lateral movement.

getherat their ends to form arectangular Certain of the frame-members are of sheet-metal pressed to a channel-section. The cross-section referred is that shown, in Fig. 1, fromwhic ,it will be seen that the frame-member consists of a base portion 3,

sides 4, 4-, a flange 5 at the inner edge, and an extension 6 at the outer edge, the latter being bent outwardly and then downwardly to form a groove at the outer edge of the framemember 9 ening downwardly. This groove is adapte to receive. a stri of wood '7, to l of the cushion may be secured by tacks 8. r

l In order to strengthen the frame members 1, 1, a plurality of sheet-metal braces *9 are, I

employed, extending transversely of the frame-members and each secured at one end to theflange 5 and at the other end to the extension 6,. In the form of cushion-shown in the drawings, only the side-members 1, 1,

of the frame are formed of sheet-metal, the p end-members 2, 2, being castings, These end-members have grooves formedtherein to receive tacking strips similar to those in the side-members and aline at their ends with the grooves in the side-members. Each of the end-members 2, 2, has integral offsets 10, formed on one side thereof, one at either end, each of these being adapted to enter the end of one of the side members 1, 1, and to be secured thereto in any suitable manner as by means of rivets.

Each of the framemembers- 1, 1, and 2, 2, supports a line of spiral springs. The s rings 11, supported upon the sheet-metal amemembers 1, 1, are secured upon the base portions 3 thereof. It will be seen that by reason of this manner of supporting these springs, the latter may be of increased lengt The springs 11 are of such size that they fit snugly between the sides 4, 4, of the frame-members. The springs 11 on the frame-members 2, 2, may be secured to the latter in any desired manner, as by bending the ends of the springs downwardly and inserting and soldering them in openings formed in the frame-members; also staples may be employed for holding the springs in osition, these staples entering openings in the rame-members and being secured therein.

Extending across the frame and secured. at their ends to opposite frame-members, are a plurality of slats 12, each of which supports a ine of spiral springs 13. These s ats are also of sheet-metal pressed into form to provide u wardly-turned flanges 14 at the lateral e ges thereof, to give them increased strength. Each of these slats is of greatest width at the points of support of the springs 13 mounted thereon, and is curved about these points somewhat, so that between each air of adjacent springs it is of least width. 11 this way, aplurality of seats for the s rings 13 'are formed and the flanges 14 at t e lateral ed es of the slats form walls which coact with t e spiral springs to prevent lateral movement thereof. At each end of eachof the slats 12, an upwardly-turned integral wall 15 is provided to facilitate securing the ends of the slats to the sides '4 of opposite side-members by means 'of rivets 16.

Secured to the upper end of the springs 11 and 13 in each line across the cushion is a flat steel spring 17, the ends of which are downwardly turned, and over each of these flat springs is laid a strip of coarse fabric 18. A covering 19, usually termed the first canvas is then drawn over the top of the cushion and its edges carried down under the frame, where they are secured to the stri s '7 by means of tacks. Upholstery material 20 is then laid over this covering and the outer covering 21 is then ap lied over the cushion, its edges being similar y carried down under the edges of the frame, where they are secured to the strips 7 by tacks.
